Page 1: Transmission Analysis: Wind Integration Study: Maine and ... · wind projects have a lower output during the summer, when demand in New England peaks. Therefore, the potential constraints

In its June 29, 2016 Comments to LUPC (“ISO Comments”), ISO-New England (ISO-NE) identifies constraints that exist in the Maine transmission system and the need for upgrades to accommodate new generation. Although constraints exist, there are a number of reasons why the existing transmission system should be able to accommodate the Bryant Mountain project.1 The map included as Exhibit A identifies Maine’s major interfaces and the key constraint areas identified by ISO-NE in its comments. This map was included in a December 18, 2014 report that ISO New England presented to the ISO-NE Planning Advisory Committee, Strategic Transmission Analysis: Wind Integration Study: Maine and Northern Vermont Updates (“2014 ISO Study”). The key interfaces are the Orrington-South interface in northern Maine, the Surowiec-South interface in southern Maine, and the Maine-New Hampshire interface at the Maine and New Hampshire border. They are depicted by the green-dashed lines on Exhibit A. There are several more localized constraint areas, shown in purple dashed lines on Exhibit A. They include the Keene Road, Wyman Hydro, and Rumford export areas. The most constrained area is north of the Orrington-South interface and, in particular, north of Keene Road. ISO-NE notes in its comments that the major constraint that affects new wind generation is located in northern Maine. (ISO Comments at pp. 2-3.)

The northern Maine constraint identified by ISO-NE does not affect the Bryant Mountain project, which is located south of Rumford and therefore is not affected by the constraints in the system to the north.

The Bryant Mountain project is subject to the Surowiec-South and Maine-New Hampshire interfaces and constraints that might exist in those locations but, as discussed below, ISO-NE has studied those constraints and the impact they might have on wind generation and concluded they are minimal. In the March 28, 2016 report by ISO-NE and presented to the ISO-NE Planning Advisory Committee Meeting, 2015 Economic Study Strategic Transmission Analysis – Onshore Wind Integration Draft Results (“ISO Economic Study”), it was determined that Maine Interface Upgrades would produce: “Little to no savings: Infrequent interface constraints and small amounts of bottled-in energy.”2 Meaning that because wind generation is not constrained for significant amounts of time, there would be minimal economic benefit to 1 As discussed in my initial June 29, 2016 Letter that was Exhibit B to EverPower’s pre-filed testimony, the project will undergo a multi-year system impact study at ISO-NE that will identify any specific upgrades required as part of the project interconnecting with the electrical grid. The costs of those upgrades will be paid for by the generator.

2 A complete copy of the ISO Economic Study is included as Exhibit C. This reference is on slide 14 associated with dispatch scenarios 1,2,3 and 4, which are existing generation plus generation north of Suroweic interface 453, 623, 857, 1149MW.

implementing upgrades to reduce or eliminate those constraints. Further, upgrades associated with projects as required by ISO-NE studies actually often increase transmission capacity and reduce congestion on the system.

When ISO-NE discusses capacity of the existing transmission system, typically it is evaluating the ability of the system to operate during periods of peak demand. Wind resources typically do not operate at maximum capacity during periods of peak demand. For example, wind projects have a lower output during the summer, when demand in New England peaks. Therefore, the potential constraints identified by ISO-NE, which occur during periods of peak demand, typically do not limit operation of wind power projects. This is evident in Exhibit B, which includes several slides from the ISO Economic Study. Slide 61 depicts flows across the Maine-New Hampshire interface and shows that during 2015 that interface was not constrained for wind or any other resources. Similarly, Slide 53 depicts flows across the Surowiec-South interface and shows that during 2015 that interface was not constrained for wind or other resources. It is possible those interfaces could be constrained during periods of higher demand not experienced in 2015, and ISO-NE specifically evaluated the potential for constraints at those interfaces under several hypothetical scenarios. The ISO Economic Study evaluated several scenarios, including a scenario in which all of the wind that was in the ISO-NE queue as of April 1, 2015 (identified as Scenario 6 on Slide 8 of Exhibit B, and which includes approximately 3,727 MW of wind power in addition to the 453 MW of wind power that was then in service in Maine) was operating. Under this scenario, there would be significant constraints at the Orrington-South interface, but no constraints at the Maine-New Hampshire interface, and minimal constraints at the Surowiec South interface. Exhibit B Slide 15. This study takes into account the variable nature of wind generation and aligns it with load as well as price signals which encourage other generators to operate, and as such it provides a more complete picture of the impact that existing transmission constraints might have on operation of existing and new wind resources.

In short, although there are constraints in the existing system, the Bryant Mountain project is not located in the areas of most significant constraints. Additionally, the constraints do not significantly affect wind resources, which do not operate during periods of time of maximum constraint in the system.

It has also been noted that there is a significant volume of wind generation proposed in the ISO-NE generation interconnection queue. Not all projects in the interconnection queue proceed to the next phase of study or are ever built. For example,3 since 1996, less than 5,000 MW out of a total of 65,000 MW of proposed interconnections (including Elective Transmission Upgrades, which may only be elimination of congestion bottle necks vs. actual new generation) proceeded to the stage of filing an Interconnection Application. (The information from 1996- 3 Based on the ISO New England Generator Interconnection Queue as of 7/28/2016

2004 is limited and it is likely the number of proposed interconnections is even higher.) In recent months, there have been a number of market signals (for example, Massachusetts, Rhode Island and Connecticut have issued a joint request for clean energy and transmission to deliver that clean energy) that have promoted competing applications of renewable generation into the ISO-NE queue, much of which will never come to completion. As reflected in the ISO Comments, the majority of proposed wind development in Maine is in northern Maine, Aroostook County. (ISO Comments at 3.) There is only minimal new generation proposed in Oxford County (63 MW, which includes the 40 MW Bryant Mountain project).

Overview

• The ISO is performing three 2015 Economic Studies – Keene Road area wind development and analysis of local interface constraints

(request by SunEdison) – Offshore Wind Deployment (request by Massachusetts Clean Energy Center) – Maine Upgrades Identified in ISO-NE’s Strategic Transmission Analysis for Wind

Integration – Onshore Wind (request by RENEW Northeast)

• Today the ISO is seeking PAC input on the draft results of the Strategic Transmission Analysis – Onshore Wind – Estimate extent that transmission constraints are binding – Measure the economic benefits of relieving those transmission system constraints

• This analysis includes future resources in some scenarios, but may not account for all the necessary transmission facilities associated with the interconnection of the resource – All future constraints may not be captured in this analysis

• Final study results and report will be completed after consultation with the PAC – The results may be used to inform the region on the needs for future transmission

upgrades in the Maine area

Background Strategic Transmission Analysis

• ISO-NE conducted the Strategic Transmission Analysis for Wind Integration (STA-WI)

• Designed to understand transmission constraints in Maine affecting wind resources in northern New England

• Focused on potential upgrades that would not require major new transmission construction

2012-2014

• ISO-NE will conduct an updated Strategic Transmission Analysis for Maine as discussed in 3/28/2016 PAC agenda item 2.0

• The Maine transmission topology has changed

• Some upgrades identified in the previous study have been implemented

• Some upgrades are no longer appropriate for current system

Background 2015 Economic Study of Strategic Transmission Analysis – Onshore Wind

Study Objective: Evaluate the impact of increasing transfer capability along the Maine corridor

– The effect of increasing transfer limits of major ME interfaces • Were identified in the Strategic Transmission Analysis – Wind Integration • Higher ME interface limits are not directly attributable to specific

transmission upgrades

– Pre-contingency thermal limits are respected in the Gridview software • Operation of wind resources can be constrained by local thermal limits

– Other local constraints are not modeled • Local, voltage and stability constraints

– E.g. Keene Road, Wyman and Rumford areas

• Could constrain the operation of impacted resources

Summary of Draft Results Study Year 2021

• For 453 MW to 1,149 MW of total wind integration in Maine – $0M to $5M production cost savings due to increasing Maine corridor interfaces – Orrington South interface becomes more constrained as more wind resources are

added

• With 2,084 MW to 3,727 MW of total wind integration in Maine – $31M to $75M production cost savings result from increasing the Maine interface

transfer limit constraints – Orrington South interface is the major constraint

• Most wind resources are located north of Orrington South • Affects the ability to transport economically dispatched resources to South of Orrington

(including New Brunswick imports) – Relieving the Maine corridor results in the North-South interface becoming

increasingly constrained

• Reminder that the above calculations are associated only with the changes in transfer capabilities on the major interfaces – Bottled-in energy was observed due to both interface and local thermal constraints – Study does not reflect influence of future interconnections on local system

CO2 Systemwide Reductions due to ME Interface Upgrades (kton**) Changes (%) in CO2 emissions are small relative to systemwide emissions of 32,000 kton/year

19

Scenarios CO2 Reduction Cases Show

kton (%) Overall, as wind penetration increases,

there is more CO2 reduction due to Maine

interface upgrades.

Negative CO2 reduction occurs in cases 2 and 3 due to change in unit

commitment after Maine interface

upgrades. The system conducts least-cost

dispatch and not least-emission dispatch. ($20

MA Based Study Results We Compared Impacts Across Amenities and Disamenities

Although the study found the effects from a variety of negative features

…and positive features…the study found no net effects due to the

arrival of turbines”. (p. 1)

Overall Conclusions

• Consistent property value impacts have failed to emerge near turbines in US

• Reasons for this include: – Significant compensation for schools and local

economies

– Relatively high levels of support for turbines

– Sorting over time to more supportive communities

• As turbines get quieter, if compensation schemes are consistently applied, and if the community is regularly involved in the development process adverse effects are likely to continue to be elusive.

LBNL Survey Results Will Shed More Light On Levels Of

Support, Opposition & Annoyance Near US Turbines

Conclusions

• Bryant Mountain Wind Farm is needed for Maine to meet its wind energy goals. Good sites are very far and few between. When you find a good site, it needs to be realized.

• Bryant Mountain satisfies the siting criteria for successful wind development

• We would like LUPC to maintain the current zoning so that we can:– Reach out to all local landowners and towns and determine if project

is compatible with the needs of the community– Develop appropriate community benefits packages the meet the

community’s needs– Conduct all wildlife and resource value studies to determine whether

there are site specific consideration that make development inappropriate

Page 185: Transmission Analysis: Wind Integration Study: Maine and ... · wind projects have a lower output during the summer, when demand in New England peaks. Therefore, the potential constraints

Conclusions

• If in two-three years, the site remains viable, we would submit an application to DEP

• There would be a complete and robust review process with opportunity for:

– Public input

– Agency input

That would ensure that the project is permitted only if the site is, in fact, appropriate for wind development.

Location of Development

GOAL: Guide the location of new development in order to protect and conserve forest, recreational, plant or animal habitat and other natural resources, to ensure the compatibility of land uses with one another and to allow for a reasonable range of development opportunities important to the people of Maine, including property owners and residents of the unorganized and deorganized townships.

Milton is located on periphery of LUPC jurisdiction• Surrounded by 4 organized towns

• Most areas within 10 miles are in organized towns

LUPC Policies• “guide development to areas near existing towns and

communities”

• “energy facilities are best located in areas on the edge of the jurisdiction with good existing road access but low natural-resource values”

Page 196: Transmission Analysis: Wind Integration Study: Maine and ... · wind projects have a lower output during the summer, when demand in New England peaks. Therefore, the potential constraints

Economic Development

Wind is compatible with forest management• Provide value to forest landowners

• Provide benefits to Oxford County, including $320k+ /year in taxes, $48k+/ year for community benefits to the host community, and $50k/year to fund local projects.

LUPC Policies• “encourage forest … and other resource-based industries”

• “encourage economic development in those areas identified as most appropriate for future growth”

GOAL: Encourage economic development that is connected to local economies, utilizes services and infrastructure efficiently, is compatible with natural resources and surrounding uses, particularly natural resource-based uses, and does not diminish the jurisdiction’s principal values.

Energy Resources

Renewable energy provides benefits to Maine• Existing capacity built thru small-medium projects

• Resource-based economic development consistent with state energy policies

LUPC Policies• “support indigenous, renewable energy resources”

• “accommodate energy generation installations that are consistent with state energy policies”

• “new renewable energy projects displace … fossil fuels and carry benefits”

GOAL: Provide for the environmentally sound and socially beneficial utilization of indigenous energy resources where there are not overriding public values that require protection.

Scenic and Recreation

Resources located outside Milton• Limited recreational opportunities within Milton

• No lakes or ponds within Milton

• Nearest scenic resource in LUPC is in Albany

• Detailed survey of resources conducted as part of permit application to DEP

LUPC Policies• “encourage patterns of grown to minimize impacts on natural

values and scenic character”

• “identify and protect areas that possess scenic features and values of state or national significance”

GOAL: Conserve the natural resources that are fundamental to maintaining the recreational environment that enhances diverse, abundant recreational opportunities.

GOAL: Protect the high-value scenic resources of the jurisdiction by fitting proposed land usesharmoniously into the natural environment.
